The script starts by retrieving inputs - the velocity input and the coordinate space. For example, if you double-click on the Add Velocity module to take a look inside, you can inspect the data flow. You can even copy and create your own modules. You can double-click any module from an emitter in Niagara to take a look at the math that's happening inside.

You can even write HLSL code inline, using the CustomHLSL node in the Graph. You can create functions, include inputs, or write to a value or parameter map. Modules are built using High-Level Shading Language (HLSL), but can be built visually in a Graph using nodes. You pass some data into the module, then inside the module you do some math on that data, and then you write that data back out at the end of the module. You can think of a module as a container for doing some math. Modules are processed sequentially from top to bottom. You add modules to groups to make a stack. Modules are the basic building blocks of effects in Niagara. There are many different renderers to choose from and experiment with. Or, you may want to use a sprite renderer and define your particles as 2D sprites. You may want to use a Mesh renderer if you want to define a 3D model as the basis of your particles, upon which you could apply a material. This is where you define the display of the particle and set up one or more renderers for your particles. Then you can create Listening events in other emitters which trigger a behavior in reaction to that generated event. In the Event Handler group, you can create Generate events in one or more emitters that define certain data. You may even want the particles to change size over time. Or, if the particles are affected by forces like gravity, curl noise, or point attraction. For example, if the color of the particles is changing over time. You will want to define here anything that needs to change frame-by-frame as the particles age. This group is called per particle on each frame. This is where you will want to define the initialization details of the particles, such as the location where they are born, what color they are, their size, and more. This group is called once per particle, when that particle is first born. Use this group to define spawning of particles when you want them to continue spawning on every frame. This group defines emitter-level modules that occur every frame on the CPU.

Use this group to define initial setups and defaults. This group defines what happns when an emitter is first created on the CPU. Inside that stack is several groups, inside which you can put modules that accomplish individual tasks. An emitter controls how particles are born, what happens to that particles as they age, and how the particles look and behave. The Timeline panel in the System Editor shows which emitters are contained in the system, and can be used to manage those emitters.Įmitters are where particles are generated in a Niagara system.

You can modify some system-level behaviors that will then apply to everything in that effect. Inside that system, you may have different building blocks that stack up to help you produce the overall effect. In the Niagara VFX system, there are four core components:Ī Niagara system is a container for everything you will need to build that effect. Beginners can start out by modifying templates or behavior examples, and advanced users can create their own custom modules. With Niagara, the technical artist has the ability to create additional functionality on their own, without the assistance of a programmer. Niagara is Unreal Engine's next-generation VFX system.
